(Code No. 68121) CH2 OH CH2OH 59 g. of l-(m-trifiuoromethyl phenylamino)-2,3-prol panediol and 118 g. of ethyl carbonate are introduced into a distillation apparatus. The mixture is progressively heated to about 110 C. when dissolution is obtained.

0 a Then, 12 ml. of a 5% solution of sodium methylate in in which R is H C1, F, CH3 or The compounds are methanol is added thereto. The distillation of the ethanol prepared by cyclizing with ethyl carbonate, a compound formed durmg the course of the reactlon is then obof the'formma 3 p I 7 served. Upon completion thereof any excess ethyl carr bonate 1s removed under reduced pressure and the resi- HZ CHOH CHZOH due obtained is crystallized in isopropyl ether.

The present invention concerns novel derivatives of 5- The compounds of Formula I experimentally exert antihydroxymethyl-3-substituted-2-oxazolidinones, their procdepressive, myorelaxing, tranquillising, sedative, analess of preparation and their therapeutic application. g l f pl -pyr g nfl mmatory and Thecompounds according tothe present invention coruricosuric act1v1t1es. Moreover, then tox1c effects on amrespond to h general f rmula; mals in the laboratory are llttle marked.

(1) Anti-depressive properties-The compounds of Formula I are capable of opposing hypothermia and the N 0 ptosis provoked by reserpine in the rat and the mouse, R as well as the ulcers provoked by reserpine in the rat. ll Moreover, they oppose the catalepsy provoked by prov I chlorperazine in the rat.

By way of example, several results obtained are listed compounds of Formula I are listed in the following in the following table: tablei TABLE II Ptosis Hypothermia Rat Mouse Ulcers Effect, Efiect, Effect, Effect, Code No. Dose C.

(IV) Analgesic activity.-This activity is particularly pronounced against the painful stretching provoked in the mouse by the intraperitoneal administration of phenyl benzoquinone or acetic acid.

The results obtained with two compounds of Formula I are shown in the following table:

TABLE V Protection against phenylbenzoquinone Dose in Effect, Code No. mg./kg./p.o. percent (V) Anti-convulsive properties.The compounds of Formula I exert in the mouse an antagonism against the lethal effects of cardiazol, strychnine and nicotine. They equally show activity against the tonic hyperextension of an excessive electric shock.

By way of example, the results obtained with several l Expressed in mg.lkg./p.o.

(VI) Anti-pyretic action.This action is manifested by a diminution of the experimental fever provoked by the administration of harm in the cat.

(VII) Anti-inflammatory effect.-The under-plantar oedema provoked in the rat by the administration of carraghenine is diminished by the compounds of the present invention.

(VIII) Uricosuric acti0n.After repeated oral administration in the rat, the compounds of Formula I provoke an augmentation of the urinary eliminations of uric acid.

In consequence of the results shown above, and the values appearing in the following table, the difference between the pharmacologically-active dose and the lethal dose is sufficiently great to enable the compounds of Formula I to be utilised in therapeutics.

TABLE VII Code No.: LD5O P.O. (mouse,) mg./kg. 67360 l600 68121 1400 The compounds of Formula I are indicated in the case of depression and neurosis by depressive and anxious components. They equally possess a favourable effect against contractural and inflammatory pains, with or without hyperthermia.

They may be administered in the form of tablets and gelules containing 50 to 250 mg. of active ingredient.

Hence, according to the present invention there is also provided a therapeutic composition comprising a compound of Formula I together with a therapeuticallyacceptable carrier.
